Dreamcast Zip Drive?

Right, I was just bored and was looking through some threads on various sites about making a hard drive for the Dreamcast and I had a random thought - this has probably been covered many times before though?

The Dreamcast had a Zip Drive made (and recently sold on ebay) that actually worked with the Dreamcast - so would it be possible to make a Dreamcast Zip Drive work like a hard drive would?
I have read that Iomega who made the DC ZD have said that the DC ZD is basically exactly the same as a PC one with alittle 'tweaking' - would it be possible for someone to get one working with a DC now?
